    On an ideal inclined plane, why does lifting a load with a ramp require less force than lifting it vertically?

    Answers

    Because the effective mass of the object is reduced
    Because force is exchanged for distance: the total work to gain the same height is similarCorrect
    Because gravity stops acting
    Because potential energy decreases

    The simple machine reduces force by increasing travel. Without losses, the work to raise the same height (mgh) is conserved.
